COMMONS Leader Andrea Leadsom has admitted she has “grave concerns” about Speaker John Bercow’s “damaging” decision to allow Dominic Grieve’s amendment to be voted on by MPs.

The amendment forces Theresa May to come back to Parliament after just three working days with a Brexit plan B. Mr Bercow has been accused by Brexiteer MPs of being biased against the Government in the dramatic break of precedent. Ms Leadsom said on ITV Peston: “My concern, my very grave concern is that the role of the Speaker of the House of Commons is to be the guardian of the rules that the House of Commons abides by."
